Pemko 18100CNB36 36" 3' 180 Degree Aluminum Retainer Weatherstrip with 1" Nylon Brush Clear Aluminum Finish

The 18100CNB36 aluminum retainer weatherstrip seals gaps under and around doors where air infiltration creates energy loss and comfort problems. This 36-inch brush seal installs on door frames and thresholds to block drafts, dust, and moisture penetration. Pemko designed this 180-degree retainer with densely compressed nylon filaments that flex and conform to surface irregularities for consistent contact.

The 1-inch nylon brush extends from a 7/8-inch aluminum casing for total height of 1-7/8 inches. Clear anodized aluminum finish resists corrosion and wear. Mounting hardware included for direct attachment to door frames or thresholds. The flexible nylon bristles maintain sealing contact as doors open and close repeatedly.
